State, local, and even local utilities subsidize them.
To be honest, I switched on my own accord. My living/dining room has several recessed light fixtures, and the halogen bulbs sucked up watts and didn't last long. I replaced them with CFL's along with just about every other fixture and lamp. My wife doesn't like them because the look ugly in the recessed fixtures, but she is okay with savings. You cannot use a dimmer on a CFL either, so it has negatively impacted my sex life :)
My problem with all of this is; when are we going to let individuals make their own decisions. If as a society we are that stupid, then just let us destroy ourselves and get it over with, because it is going to happen sooner or later. We should be able to vote with our dollars on what kind of light bulb we want to use. With a little math calculation, and the benefits of reduced energy consumption, most people would probably switch to CFL's on their own, and it would cost us less tax money. There are so many laws and regulations introduced every single year, it is impossible to keep up with them, and to research the feasibility of each... even our elected representatives have to hire aides to wade through all of it. And the more we let government make our decisions, the crazier it gets. Where I live you have to get government permission on the color you want to paint your commercial building, and how much open space and types of plants you can have in new construction. Want to build a new house... you must put up a block wall, materials determined by the city. I am fighting the city right now because I removed a fence between my yard and my neighbor's... I like open space and it was my fence. If the neighbor wants a fence, then he can build a new one on his side, but he doesn't care either way. But I unwittingly violated the law; silly me I thought it was my property. You are restricted to what kind of vehicle you can park in your driveway, you are not allowed to use natural fertilizers because the odor might be offensive (only chemicals are allowed), and certain times of the week we are not allowed to ride a camel on the main street in town. And we have people running all over town enforcing these rules. But if you are attacked by a vicious dog in the street, good luck getting quick response to a 911 call. And god forbid you want animal control to pick up a stray animal... last time I had a problem the city made me RENT a trap and capture it myself. We vote the idiots out, and then a new group of idiots are elected by stupid people. Or we have agencies that can pass regulations without our approval, and we cannot remove them, because they are not elected positions. It seems we think that government must pass new laws and regulations, or they did not do their job. I would like to see each session of Congress try and reduce laws and regulations by 10% instead. See, I am an optimist. I think that people can make good decisions once they figure out they are own their own and government will not take care of them. Democrats, Republicans, Libertarians, Tea Party... we need to get rid of all of them. Hopefully more and more people will register independent and each candidate will have to appeal to the majority, not the party with the most money to spend. That is how we will take our power back.
